If you look at the following file, you'll see it links to Foundation  
(the first item in the list):

# otool -L BuildRoot/usr/bin/arch
(compatibility version 300.0.0, current version 677.19.0)
	/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current  
version 1.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current  
version 111.1.1)
	/usr/lib/libobjc.A.dylib (compatibility version 1.0.0, current  
version 227.0.0)
CoreFoundation (compatibility version 150.0.0, current version 476.13.0)

So move arch out of the way:

# mv BuildRoot/usr/bin/arch BuildRoot/usr/bin/arch.bak

And replace it with a shell script like the following:

/usr/bin/uname -m

... and make it executable:

# chmod a+x BuildRoot/usr/bin/arch

(Note that when the build is in progress, it is chrooted, so "/usr/ 
bin" in the shell script is really "BuildRoot/usr/bin")

Darwinbuild does not wrap the target in quotes, so the following  
forces a set of quotes to make it into the xcodebuild command:

darwinbuild -target="\"pppd (Tool)\"" ppp
